To all whom it may concern:

Be it known that I, J AMEs AUGUSTUS DOBEY, a citizen of the UnitedStates, and a resident of Johnston, in the county of Edgefield and Stateof South Carolina, have made certain new and useful Improvements inMasks, of which thefollowing is a speci fication. Y

My invention is an improvement in masks, and has for its object toprovide a device of the character specified adapted for use by doctors,nurses and the like, when in the presence of patients suffering frominfluenza, meningitis, and other diseases communicated throughdischarges from the nose and mouth.

In the drawing Figure l is a perspective view showing the improved maskin use.

Fig. 2 is a perspective view of the mask looking inside.

Fig. 3 is a side view.

Fig. at is a plan view of the cover.

Fig. 5 is a perspective view of the frame.

Fig. 6 is a sectional view showing the means for supporting a pledget ofcotton at the nostrils.

Fig. 7 is a perspective view of the cover and its connecting frame. Inthe present embodiment of the invention, a suitable supporting frame 1is provided of oblong looped shape, the said frame being of less widthat its top than at its bottom and shaped to fit from the junction of thenose with the forehead to beneath the chin.

The large end of the loop is of sufficient width to-fit about the chin,and beneath the same. Cross wires 2 and 3 complete the frame, the saidwires being arched as shown and arranged with the arch inthe same di- 7rection. These wires 2 and 3 have their ends lapped about the loop wire1, and they are designed to hold the cover well away from the nose andmouth to provide breathing space.

The cover for the frame,'which'is of as shown at 6 in Fig. 7, so thatthe loop Copies of this patent may be obtained for Specification ofLetters Patent.

may be enlarged to permit it to be fitted over the frame 1 and into theframe as shown in Fig. 3.

A pledget 7 of cotton or like absorbent material may be connected withthe body of the arch 3, the said pledget being adapted to hold anantiseptic or the like.

The improved mask may be held on the face over the nose and mouth bymeans of a cord 8, which may be connected to'the frame 1 at the ends ofthe arch 2.

In placing the cover on the frame 1, 2, 3, the frame 5 is enlarged untilit will pass around the frame 1. It is then contracted until it passesthrough the frame 1 on the same side as the arches 2 and 3. Here the 7is connected, the ends of the loop being slidable upon each other andsaid loop being adapted to be passed over the loop of the first namedframe, and through the loop of the frame to hold the cover in place.

2. A mask comprising a loop shaped frame, a cover for the frame, a splitloop shaped frame to which the edge of the cover is secured, said splitloop being adapted to be passed over the loop of the first named frameand through the loop and to beexpanded between the loop and the body. of
